Matthew 19:5

ἕνεκα τούτου. The lesson of Nature is the lesson of God, ‘Nunquam aliud Natura aliud Sapientia dicit.’ Juv. Sat. XIV. 321.

κολληθήσεται. This word and the compound προσκ. in N.T. use are confined to St Paul and St Luke except Revelation 18:5. This passage and Mark 10:7 (where the reading is doubtful) are quotations. The classical meaning of κολλᾶν is (1) to glue; (2) to inlay; (3) to join very closely: κεκόλληται γένος πρὸς ἄτᾳ, Æsch. Ag. 1566.

εἰς σάρκα μίαν. εἰς denotes the state or condition into which a thing passes. The construction follows the Hebrew idiom.
